4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann arnd@arndb.de
When CONFIG_MTD_CFI is disabled, we get a warning for this spi driver:
include/linux/mtd/cfi.h:76:2: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. [-Werror=cpp]
The problem here is a layering violation that was fixed in mainline kernels with a larger rework in commit 054e532f8f90 ("spi: bcm-qspi: Remove hardcoded settings and spi-nor.h dependency"). We can't really backport that to stable kernels, so this just adds a Kconfig dependency to make it either build cleanly or force it to be disabled.
